Abstract
In a recent paper, “Arbitrary amplitude ion-acoustic supersolitons in negative ion plasmas with two-temperature superthermal electrons” [Phys. Plasmas 29, 092101 (2022)], Kumar and Mishra deal with the study of ion-acoustic solitary and supersolitary waves in a four-component plasma consisting of positive ions and negative ions along with two temperature superthermal electrons. Unfortunately, the reported results are incorrect.
